Modules of music
Another music format that can be used is the module format range (.xm, .it, .mod, .s3m,
and many other extensions). These music files are of much smaller size than MP3s as they store instruments and patterns of music to play rather than continuous sound wave data. This makes them great for video games.
Although we already have music in our game, we'll take a look at how we could have added module music to our game in order to know how to do it in future games.
